[0008]

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a bogie entrance provided at the center, a tray extruding part disposed on one side of the bogie entrance, and
Trays constituted by a tray receiving portion arranged on the other side of the cart entry portion, and a tray delivery mechanism for sending out a row of trays transferred to the receiving tray of the tray receiving portion to a conveyor device outside the device. This is a device for taking out from the rack.

The carriage entry section is a position where the carriage enters and stops there, has a required width, and includes appropriate stopper means for stopping the carriage.
The cart has a plurality of racks and a caster at the bottom, and each rack has a width enough to stack and load a plurality of trays in two rows. About three to four racks are appropriate.

[0010] The tray pushing section is disposed on one side of the carriage entry section. The tray extruding unit is an extruding mechanism that pushes out two rows of trays stacked on the racks of each stage of the bogie that has stopped at the central bogie entrance, one row at a time on the front side, and thereby extrudes one row toward the other side. And a lifting mechanism that raises and lowers this pushing mechanism to match the height of the rack at each stage of the cart.

[0011] The pushing mechanism pushes out a group of trays stacked and placed in two rows on the rack of each stage of the cart, and sequentially pushes the rows toward the other side by pushing one row in front of the tray group. It is not limited to a specific one as long as it can do it. For example, an air cylinder or the like is used, and an extruding plate having a width and a height capable of pushing a row of trays is attached to the tip of a rod that moves forward and backward, and the like is effectively used.

The lifting mechanism is not limited to a specific configuration as long as the pushing mechanism can be moved up and down as described above. Various configurations can be freely adopted.

For example, nut members are arranged at four corners of a frame that supports the pushing mechanism, and screw members that stand upright are respectively screwed with the nut members, and the screw members are rotated forward or backward in conjunction with each other. This makes it possible to adopt a configuration in which the frame is raised and lowered. Alternatively, short pipe members are arranged at four corners of a frame supporting the extrusion mechanism, and upright support pipes are inserted into the respective pipe members, and chains are connected to a plurality of positions of the frame, and And a balance weight is inserted between the pulleys of the respective chains while hanging over the respective pulleys of the respective chains, and a lower end of each of the chains is further wound around an electric motor. It is possible to adopt a configuration in which the take-up mechanism or the take-up mechanism is coupled to the take-up mechanism.

The tray receiving portion includes a receiving tray for receiving a row of trays extruded by the extruding mechanism of the tray extruding portion, and moving the receiving table to a position close to a corresponding rack prior to the pushing of the tray by the extruding mechanism. Advancing and retreating mechanism for returning to the original position after receiving the tray, and an elevating mechanism for moving the receiving table up and down to a rack at the stage where the tray is pushed out by the pushing mechanism or a sending position of a tray described later. It consists of.

The receiving table has a sufficient area for mounting a row of trays, and has a sufficient strength to receive the weight of the trays, and can move forward and backward within a predetermined range. What is necessary is just what is comprised as above.
The forward / backward movement may be performed, for example, by disposing a guide rail on a frame supporting the guide rail and sliding the guide rail on the guide rail. Of course, there is no inconvenience in other configurations.

As described above, the advancing / retracting mechanism is not limited to a specific configuration as long as it can advance the receiving table to a predetermined position and return to the original position. Any suitable configuration can be freely adopted. For example, it is possible to adopt a configuration in which an air cylinder is adopted, the inner end of the receiving table is connected to the tip of a rod that moves forward and backward, and the receiving table moves forward and backward by the rod moving forward and backward.

The lifting mechanism may have a specific configuration as long as the receiving table can be moved up and down to a rack at a stage where the tray is pushed out by the pushing mechanism or a tray feeding position to be described later. There is no reason to limit it. A configuration having a necessary function can be freely adopted. Thus, for example, it can be configured in exactly the same manner as that of the tray extrusion section.

As described above, the tray feeding mechanism moves the row of trays transferred to the tray receiving table of the tray receiving section at the tray feeding position at the same height as the receiving position of the conveyor device outside the device. This is a device for sending out to a conveyor device. If the upper surface of the conveyor device outside the device is set at the same height as the upper surface of the receiving table lowered to the bottom, the height position is the tray sending position, and the tray is sent from that position to the receiving position of the conveyor device. Needless to say.

The tray feeding mechanism is not limited to a specific mechanism as long as it can feed the tray placed on the receiving table. Although there are various sending directions, it is configured so as to be able to send at least a fixed direction. It is convenient if it can be sent out in various directions according to the surrounding conditions.

The tray feeding mechanism includes, for example, a guide bar arranged along the receiving table, an extruding plate moving on the receiving table along the guiding bar, and a reciprocating mechanism capable of reciprocating the extruding plate along the guiding bar. And a drive mechanism. The reciprocating drive mechanism includes, for example, an endless chain having a return side and a carrier side arranged along a guide rod, a pulley extending around the end of the endless chain near both ends of the guide rod, and forward and reverse rotation of the endless chain. And an electric motor to be moved. In this case, if the extruded plate is connected in the middle of the endless chain, it can be reciprocated.

When such a tray feeding mechanism is used, it goes without saying that the tray can be fed in the moving direction by the forward movement of the push plate.

Therefore, according to the apparatus for removing trays from a rack according to the present invention, the trays are easily and safely stacked in a plurality of racks in a row or two rows, and a plurality of trays are stacked and placed on a cart. The tray as it is can be taken out and transferred to another conveyor device.

The bogie enters the central bogie entry section and stops at an appropriate position. The tray loaded on the trolley is removed from that of the uppermost rack in consideration of the weight balance of the trolley.

On the one hand, the raising and lowering mechanism of the tray pushing section arranged on one side of the carriage entrance section is operated, and the pushing mechanism is moved up until it coincides with the position of the uppermost rack. Similarly, the tray of the tray receiving section arranged on the other side of the carriage entrance section is moved upward by the elevating mechanism until it coincides with the position of the uppermost rack, and further, the advancing / retreating mechanism is operated. To the position close to the rack.

Thereafter, the pushing mechanism of the tray pushing section is pushed out to push the two rows of trays placed on the uppermost rack of the carriage toward the receiving side of the tray receiving section.
The two rows of trays directly stop at this stage, pushing one of the rows closer to the extrusion mechanism and pushing the far one of them onto the receiver. From the viewpoint of transfer to a conveyor device outside the device, the trays are sent out one row at a time. In this state, the pushing mechanism stops and enters a standby state.

On the other hand, when the receiving table receives a row of trays as described above, the advance / retreat mechanism performs a retreat operation to return the receiving table to the original position. Thereafter, the elevating mechanism of the tray receiving section is operated to lower the receiving table and move the tray to the tray sending position at the same height as the receiving position of the conveyor device outside the device. If the bottom is at that position, move to the bottom.

When the receiving table moves down to the tray sending position, the tray sending mechanism operates to send a row of trays placed thereon to a conveyor device installed outside the device.

When the tray feeding operation of the tray feeding mechanism is completed and the mechanism returns to the original state, the elevating mechanism operates to raise the receiving table to the uppermost position,
When the receiving table further rises to the uppermost position, the advance / retreat mechanism operates to move the receiving table to a position close to the uppermost rack of the truck.

At this point, the extruding mechanism, which has been in the standby state in the above state, starts operating, further advances, and advances the remaining one row of trays again to a position close to the uppermost rack. Extrude onto the receiving platform.

The extruding mechanism that has pushed out the remaining row of trays in this manner then returns to its original position, and then the elevating mechanism operates to move the extruding mechanism to a height corresponding to the second rack from the top. And lower it. In addition, the receiving table receiving the remaining one row of trays operates the advancing / retreating mechanism to return to the original position, and then the elevating mechanism operates to descend to the tray sending-out position, and then thereafter, as described above.
A row of trays placed thereon is fed to a conveyor device outside the device by the operation of the tray feeding mechanism. When the trays are sent out in this manner, the receiving table is moved up by the operation of the elevating mechanism to a height corresponding to the second rack from the top of the bogie.

Thereafter, the two rows of trays placed on the second rack from the top of the cart are moved to the top rack of the cart by the tray push-out section, tray receiving section and tray delivery mechanism. The take-out operation is performed in the same manner as performed for the two rows of trays that have been placed. The same applies to trays placed on a rack further below.

Therefore, according to the apparatus for removing trays from a rack of the present invention, a tray placed on a rack of a cart can be safely and reliably transferred to a conveyor device outside the apparatus.

Further, according to the apparatus for removing trays from the rack of the present invention, since the pits are not formed on the floor, the apparatus can be easily configured, and the layout in the work place can be easily changed. sell. Also, since there are no low places like pits, there is no room for problems such as drainage pumping.
